祁子堂金矿区位于北秦岭褶皱带东段南支,地质构造复杂,岩浆活动频繁。金矿赋存于碎裂白云石大理岩与斜长角闪片岩互层部位,受北西西向断裂控制,矿体围岩蚀变以硅化、褐铁矿化为主,属于低温热液构造蚀变岩型金矿床。分析该矿床地质特征及矿床成因,总结其找矿标志,对祁子堂矿区及其外围的找矿工作具有指导意义。
祁子堂金礦區位于北秦嶺褶皺帶東段南支,地質構造複雜,巖漿活動頻繁。金礦賦存于碎裂白雲石大理巖與斜長角閃片巖互層部位,受北西西嚮斷裂控製,礦體圍巖蝕變以硅化、褐鐵礦化為主,屬于低溫熱液構造蝕變巖型金礦床。分析該礦床地質特徵及礦床成因,總結其找礦標誌,對祁子堂礦區及其外圍的找礦工作具有指導意義。

The Qizitang Gold deposit filed is affiliated to the south branch of the east section of North Qinling Fold Belt, with complex geologic structure and frequent magma activites. Orebody occurrs in the interbedding of cataclastic dolomite-marble and amphibolites, which is controlled by NWW-trending fault. The wall rock alteration takes quartzitification and limonitization as the principal type, and it belongs to low temperature hydrothermal and altered rock gold deposit . This paper analyzes the geological characteristics of this ore district and origin of deposit and summarizs the prospecting criteria, which have certain guiding significance to ore prospecting for the Qizitang and perimeter zone.
